APPARATUS FOR PRINTING OR COLORING YARN OR SIMILAR MATERIAL.

BPIECIFLGATIUH forming part of Letters Patent No. 719,284, dated January 27, 1903.

Application filed October 25, 1897. $eria1No. 656,277, (No model.)

To (Z2 whom it may concern:

Be it known that I, \VILLIAM J. WEBB, a citizen of the United States, residing at Yonkers, county of \Vestchester, and State of New 5 York, have invented certain new and useful Improvements in Apparatus for Printing or Coloring Yarn or Similar Material, fully described and represented in the following specification and the accompanying drawings,

IO forming a part of the same.

This invention relates to improvements in apparatus for printing or coloring yarn or similar material by applying to the yarn successive streaks of color arranged side by side,

the object of the invention being to secure such approximately uniform coloring of the yarn as will finally with the aid of the usual steaming and scouring processes secure uniform appearance of the various shades in the finished yarn and in the fabric into which it is woven.

The invention will be described as applied in connection with methods and machines of a general class and now in common use for printing or coloring carpet-yarn.

In printing yarn for tapestry and other carpets the yarn is usually wound upon a drum and then the colorapplied by means of a colorapplying devicesuch as a wheel, bar, or

other equivalent devicewhich is usually a wheel and to which the generic term colorwheel will be applied herein, this wheel running in a box or trough called the colorbox, which is carried by a carriage reciproeating longitudinally of the drum. At each reciprocation of the carriage the color-wheel applies to the yarn a streak of color equal to the width of the wheel and the drum is rotated step by step for the successive streaks,

0 a wide stripe of a color being obtained by applying two or more streaks of the same color and different color-boxes and color-wheels being substituted for streaks of different colors. In this printing operation a ridge of color is formed at each side of the colorwheel-that is,bet\veen two adjacent stripes-- and it is usual to employ devices, known variously as rubbers, scrapers, spreaders, or equalizers, and to which the generic term rubbers will be applied herein, for (listributing the color contained in these ridges and rubbing the color into and through the yarn, these rubbers being mounted to reciprocate with the color-wheel and follow it in printing. Usually a pair of such rubbers are employed, located on opposite sides of the colorwheel and automatically thrown into and out of operative position to act alternately as the color-carriage moves in opposite directions and arranged so that they may both be thrown outof operative position when required to avoid rubbing streaks of different colors into each other. A single rubber may be used also and shifted from one side of the color-wheel to the other.

I so construct my improved apparatus as to permit of simultaneously rubbing the stripe of yarn upon which the streak of color has just been applied and a portion of the unprinted yarn on one side of said stripe, so as to laterally distribute the color over and rub it into the unprinted yarn, and then printing the next streak upon the yarn upon which color has been thus distributed, and I preferably so proportion my rubbing appliances as to be able to rub simultaneously a portion of the next previously-printed streak, so as to distribute the color laterally in both directions from the streak last printed and rub it into the yarn.

The color may be distributed more or less upon the unprinted portion of the yarn; but it is desirable to distribute the color over a considerable portion of the width of a streak of color, and I prefer to extend the rubbing operation over substantially one-half or more of the stripe of yarn to which the next streak of color is to be applied, and I prefer to extend the rubbing operation similarly over the next previouslyprinted stripe. 0

In carrying out this invention in apparatus for printing or coloring yarns I may use a rubber of any suitable form by making it of such width and so positioningit relatively to the color-wheel or equivalent color-applying 5 device as to subject the yarn to a rubbing op eration, as indicated above, and these rub bers may be mounted and operated in any suitable manner.

For the purpose of illustration I have shown 10o in the accompanying drawings a drum yarnprinting machine embodying my invention,

- track with both rubbers in inoperative position. Fig. 4 is a section on line 4 of Fig. 1 with the drum indicated above the colorwheel in printing position. Fig. 5 is a crosssection on the line 5 of Fig. 1 with the colorcarriage and drum omitted. Figs; 6, .7, and 8 are details of the rubber hereinafter referred to. Fig. 9 is a diagrammatic View showing in plan successive stripes of printed yarn and the relation of the rubbers thereto. Fig. 10 is a side elevation of another form of machine in which the rubbers are reversed by contact with the drum as the carriage moves beneath the drum for the printing operation, the carriage being shown as it moves toward the left toward the drum. Fig. 11 is a similar view showing the carriage beneath the drum and moving to the left during the printing and rubbing operation. Fig. 12 is a rear elevation of one of the rubbers and its mounting, the color-wheel being indicated in dotted lines projected slightly above the rubber for purpose of illustration, so as to show the sidewise relation of the rubber to the wheel. Fig. 13 is a diagram of this construction similar to Fig. 9. v

Referring now especially to the construction illustrated in Figs. 1 to 9, Ais the yarndrum, which may be mounted to rotate step by step in any suitable manner for printing the successive stripes. Below the yarn-dru m A the frame of the machine is provided with rails 10 for supporting the wheeled carriage B, which is reciprocated by a cable 11, passing over pulleys 12 and actuated in any suitable manner. Hinged at 13 in the carriage B is a plate 14, which carries the color-wheel C, runningin a removable color-box D, which is supported in an opening in said plate, the face 0 of this color-wheel O acting to apply the color to the yarn. At opposite sides of the color-box the plate 14 carries bearings 15 for the shaft of the color-wheel, by which the color-wheel may be rotated by any common or suitable means. The color-wheel is yieldingly pressed against the yarn by a spring or springs 16, secured to the carriage B and engaging the under side of the plate 14, and the upward movement of the plate and colorwheel is limited by a nut 1 on a bolt 2, passing through an opening in the end of the plate 14 and acting as. a stop for the plate. At each end of the carriage is mounted a rubber 01 cl, these rubbers being mounted on rearwardly-inclined supports 17, the outer portions of their upper surfaces forming rubbing-surfaces which in the operative position of the rubbers make contact with the yarn upon the drum. These rubbers are preferably constructed of a block of semiyielding material, such as hard vulcanized rubber, which is rearwardly beveled at its outer end to provide inclined rubbing-surfaces having the spreading or rubbing edges or the front portions of their operative spreading or rubbing faces extending in substantially straight lines over the path of the colorwheel and over portions of the adjoining unprinted yarn, which is to receive the next streak of color, and over portions of the adjoining streaks of color previously printed,

as shown and as more fully set forth herein after. It will, however, be understood that the rubbers of this machine may be otherwise constructed so far as the embodiment of the present invention is concerned. Certain more limited features of the invention, however, include certain specific features which areembodiedin the construction shown, in which the front portion of the operative spreading or rubbing face of the rubber or that portion which is in front relatively to the movement of the rubber when in operation and the spreading or rubbing edge,which in the rubber shown is the edge at the top of the inclined surface, extend in straight lines over the yarn. The connection between each rubber and its support 17 is preferably such as to permit of the adjustment of the rubber up and down, the connection in the present case being formed by mounting the rubber to slide on a dovetailed block entering a similar groove in the rubber, as shown in Fig. 8, the rubber being held in adjusted position by a set-screw 3. Thus the rubber may be readily adjusted relatively to the drum or removed for repairs or replacement. The rubbers are mounted and actuated'so as to be moved automatically into and out of position to engage the yarn, the rubber behind the colorwheel being in operation and the rubber in front of the color-wheel being thrown out of operation'as the color-wheel moves in opposite directions for printing successive stripes. For this purpose the construction shown is as follows:

Each of the supports 17 is loosely journaled on a shaft 18, carried by brackets 19 at the ends of the carriage, and each support carries a spring 20, the lower end of which engages a link 21, also journaled loosely on the shaft 18, and through which spring as the link 21 is swung outwardly the rubber is moved into and held in operative position, thus being held yieldingly against the yarn by the spring 20 whenin operation. Movementtoinoperative position is accomplished by swinging the link 21 inwardly and the engagement of a projection 4 on the hub thereof with a similar projection 5 on the hub of the support 17, as shown in Figs. 6 and 7. This movement of the rubber to inoperative position may be as- III sisted by a spring 22, connected to the link 21 and to the carriage, which spring will also assist in retaining the rubber in inoperative position. The link 21 of each rubber is provided with a slot 23, which receives a pin 6, carried by an arm 24 011 a rock -shaft 25, mounted in the brackets 19. The rock-shaft 25 carries a second arm 26, which is connected by a link 27 to a lever e or 6, corresponding, respectively, to the rubbers d 61, these levers e 6 being pivoted in suitable supports on the frame to rock vertically. Each of these levers e c has pivotally connected to its free end a depending rod 28 or 29, corresponding to the respective levers e e and rubbers d 61', these rods being provided at their lower ends with a bowl 7 for engagement with cams at opposite ends of the movement of the carriage for actuating the levers e e to throw the rubbers-into and out of operative position. The rods 28 29, levers e e, and the connection of the latter to the rubbers are arranged on opposite sides of the carriage, and the cams coacting with the bowls 7 are similarly arranged and are as follows:

The bowl 7 on rod 28 coacts with camsfg, respectively, for lowering and raising the rod 28'and the bowl 7 on rod 29 with similar cams f g, the cams for the respective rods and corresponding rubbers being reversed so that each end of the machine carries a raising and lowering cam for throwing one of the rubbers out of operative position and the other into operative position. The operation of this tripping mechanism for the rubbers will be readily understood from a brief description.

In the position shown in Fig. 1, in which the carriage has completed its movement to the left and is about to move under the drum A and toward the right for printing another stripe on the yarn, the bowl 7 on rod 28 running on the underside of the cam f as the carriage approached the end of its movement to the left has depressed the rod 28, and thus rocked the lever e, so as to raise its outer end, and thus through the link 27 and arm 26 has rocked the rock-shaft 25, so as to move the arm 24 downward, and by the pin 6 moving in the slot 23 has thrown the link 21 outward and through the spring raised the rubber cl into operative position, so that it will engage the yarn behind the color-wheel C as the color-carriage moves to the right for printing the next stripe. At the same time the bowl 7 on rod 29 running on the upper side of cam g has raised the rod 29 and rocked the lever 6, so as to lower its outer end, and thus through rock-shaft and its connections has moved the arm 24 upward and by the pin 6 moving in the slot 23 has thrown the link 21 inward, aided by the spring 22, and thus through the projections 4 5 rocked the rubber d downward from its raised operative position, in which it has acted upon the yarn during the carriage movement just completed, into its lowered inoperative position, so as not to engage the yarn in front of the color-wheel C on the next printing movement. This position of all the parts is shown in Figs. 1 and 2, the same position of the rubber d being shown also in Fig. 4.

As the color-carriage B moves to the right in printing the next stripe the rubbers d d remain in the same positions until the print ing of the stripe has been completed and the color-carriage reaches the limit of its movement to the right corresponding to its position at the left, as shown in Fig. 1, when the rubbers are reversed, the rubber d being raised into operative position by the bowl 7 on the end of rod 29 coacting with cam f and the rubber 61 being lowered into inoperative position by the bowl 7 on the end of rod 28 coacting with cam g, the action of these cams and connections to the respective rubbers being the same as previously described in connection with the reversal of the rubbers at the completion of the previous movement to the left.

It will be seen that the arms 24 in moving upwardly and downwardly, so as to move the links 21 in and out, move past their horizontal position, so that the pins 6 in the slots 23 act to lock the links and rubbers in the position to which they are thus moved, so as to lock them in operative or inoperative position.

For throwing both the rubbers d 61 out of operation, which is desirable in many cases, so as to prevent different colors being rubbed on the same surface, the camsff, by which the rubbers are thrown into operative position, are made adjustable into and out of position for engagement with the bowls 7 of the depending rods 28 29, these cams ff being shown for this purpose as carried by vertical levers 30,'pivoted on the frame of the machine and connected by links 31 to arms 32 on a horizontal rock-shaft 33, which is actuated by an arm 34, connected by a link 35 to a vertical bell-crank lever 36, connected to a treadle 37, so that by depressing the treadle the shaft 33 is rocked and through the links 31 rocks the levers 30, so as to throw the cams ff inward from the position shown in full lines in Figs. 4 and 5 to the position shown in dotted lines in the same figures, so that these cams will be inside the path of the bowls 7 and the bowls 7 will pass the cams without engagement therewith. On releasing the treadle the cams will be thrown outward into operative position by the spring 38 acting on arm 39 on the rock-shaft 33, as shown in Figs. 1 and 2, and the rubbing action of the apparatus will be resumed. The position of the parts with both rubbers in inoperative position is shown in Fig.

The relation of the rubber to the printingface 0 of the color-wheel O and to the stripes of printed yarn and ridges formed between the same is shown in Figs. 2, 4, and 9, this being the preferred width and arrangement of the rubber, the rubber being placed centrally to the colorwheel, so as to overlap equally on both sides of the stripe of yarn be- IOC &

ing printed and of such width as to distribute and rub the colorlaterally over a considerable portion, preferably substantially onehalf or more, of the previously-printed stripe of yarn and of the unprinted yarn to which the next streak of color is to be applied.

As shown in Fig. 9, two stripes 1 2, numbered in the order of printing, have been printed. Stripe 3 is being printed with the rubber in operation, and the position of stripe 4, which is the next stripe to be printed, is indicated in dotted lines, the operative surface of the rubber (1 thus actingupon the whole of the stripe 3 of yarn being printed with the ridges on each side of the same, substantially one-half of the previously-printed stripe 2 and substantially one-half of the unprinted yarnwhich will form stripe 4: when the next streak of color is applied, thus distributing and rubbing color from stripe 3 over the adjoining unprinted yarn to the extent of substantially one-half of the width of a streak of color or'printed stripe of yarn. This width and arrangement of the rubber provides for a double rubbing of all parts of the colorstreaks with the distribution of the color from each streak over such an extent of the adjoining portion of the yarn as to secure the wide distribution of the color, which is desirable for uniformity. It will be understood, however, that the rubber may overlap more or less upon the adjoining unprinted portion of the yarn, so as to secure a wider or less wide distribution without departing from the invention, considered broadly. It will be understood, also, that the rubber may overlap more or less upon the previously-printed portion of the yarn on the opposite side of the streak of color being applied and that, if it is not desired to rub the color twice in opposite directions, as by the construction shown, the rubber may be constructed and arranged so as to overlap and distribute color upon the unprinted portion of the yarn without overlapping upon the previously-printed portion of the yarn. It will be understood that both rubbers when of the width and positioned as shown will be thrown out of operation in printing the first and last stripes of a series of the same color, so that they will not be used except when at least three stripes of the same color are to be printed, and when but three stripes are to be printed the rubbing operation will be used only in printing the second stripe.

It will be understood that the invention may be applied in connection with rubbers of various forms and that when the rubbers are automatically thrown into and out of operative position any suitable devices may be used for this purpose.

In Figs. 10 to 13 I have illustrated another construction in which the rubbers are automatically reversed, so as to throw the rubber in front of the color-wheel out of operative position and the rubber behind the colorwheel into operative position by engagement with the drum itself instead of employing cam mechanism for this purpose, as in the constructions already described. In this construction the rubbers m m are mounted in rocking carriers 60, pivoted in brackets (51 on the carriage, and the carriers have depending rods 62, swinging between the arms of brackets 61 and carrying weights 63, which tend to hold the rubbers m m in vertical position, as shown in Fig. 10. Each of the carriers 60 is provided outside the bracket with an arm or lug 64, adapted to engage a spring 65, mounted on the bracket, so that the rubber is held against the yarn by the spring under yielding pressure during the rubbing operation. On the rear side of the plates forming the rubbers m m are mounted riders n n, which engage with the yarn to hold the rubber in front of the color-wheel out of engagement with the yarn, these riders being of such width, as shown in Fig. 12, as not to make contact with the previously-printed stripe of the yarn.

The width and sidewise position of the rubbers m m relatively to the face 0 of the colorwheel 0 is shown in Fig. 12, in which the color-wheel is dotted in position, with its face projected above the upper edge of the rubber for purpose of illustration. The relation of the rubber m to a series of stripes is shown in diagram in Fig. 13 in the same manner as in Fig. 9, the rubbers in this construction being shown as somewhat wider than the rubbers d 01', previously illustrated, so as to overlap substantially a half and somewhat more of the stripe of yarn 3 being printed and of the neXt previously-printed stripe 2 and the dotted stripe of yarn 4 to be printed next.

The operation of this machine in reversing the rubbers will be understood from a brief description. In the position shown in Fig. 1 the carriage is ready to move toward the left under the drum A for printing a stripe, both the rubbers being held vertically by the weights 63. As the carriage moves under the drum the rider n on the back of rubber m at the left of the carriage and in advance of the color-wheel O strikes the drum, and the rubber is thus swung rearward against the resistance of weight 63, so that this rubber m is held out of contact with the yarn as the carriage passes beneath the drum during the printing operation, the rider n bearing against the yarn, as shown in Fig. 11. When the rubber m reaches the end of the drum or edge of the yarn, which is the end of the drum, it is swung to the right against the resistance of weight 63 by the engagement of the rubber with the drum, and thus brought into position for the rubbing operation, as shown in Fig. 11, being held under yielding pressure against the yarn on the drum by the weight 63 and by the spring 65, into contact with which the arm or lug 64 on the hub of the rubber-has been then brought by this movement. This position of the parts continues during the passage of the color-can too riage beneath the drum and the printing of a stripe, each of the rubbers being returned to vertical position, as shown in Fig. 10, by the weights (53 as they pass out from beneath the drum and the operation being the same as the color-carriage moves to the right for printing the next stripe except that the rubber m then in advance of the color-wheel is thrown out and held out of operative position by the rider n and the rubber on behind the color-wheel is thrown into operative position by its engagement with the drum. No means are shown for throwing both the rubbers m m into inoperative position, and it will be understood that such a machine may be used in printing plain or solid color yarn with one of the rubbers always in operation or that both the rubbers may be removed when desired for printing stripes of different colors or moved into inoperative position and held in such position by any suitable means.
